FAQ
What do you need from me to get started?
A short description of your project, the features or endpoints you need and your preferred database. If I am working on an existing project, please share access to the code repository.
Can you work on my existing Node.js or NestJS project?
Yes. I can fix bugs, add new endpoints, improve performance or refactor your existing API. Please message me with the repository details and the issue before ordering so I can confirm the right package.
Will I own the source code?
Yes. Every package includes the full source code, and it is completely yours after delivery. I can push it to your GitHub or GitLab repository or deliver it as a zip file.
Do you provide API documentation?
Yes. The Standard and Premium packages include Swagger (OpenAPI) documentation, so your frontend or mobile team can test and integrate every endpoint quickly.
Which database and tools do you use?
I work with PostgreSQL and MongoDB, using TypeScript, NestJS or Express. Redis caching, WebSockets and Docker are added when your project needs them.
Do you offer support after delivery?
Yes. I fix any bug in the delivered work free of charge for 7 days after delivery. For ongoing maintenance or new features, I can send you a custom offer.
